Fig. 5From: Transcriptome-based gene regulatory network analyses of differential cold tolerance of two tobacco cultivarsAnalyses of the pink and brown module. A Module gene expression pattern of the brown module, red indicates high expression level and green indicates low expression level. B The correlation network of the pink module. A gene network is constructed by using WGCNA, in which each node represents a gene; the connecting line (edge) between genes represents the co-expression correlation. The genes with edge weights > 0.1 and sorting the top 50 by the number of edges are visualized by Cytoscape. The size and color of each circle represent the number of edges.
